Performance modelling and assessment of plastic tubular falling film tower for the development of low flow liquid desiccant system

Abstract

Low flow falling film liquid desiccant systems are overall efficiency and energy promising due to their economic value. Two main limitations: corrosive nature of liquid desiccant and incomplete wetting of the working surface hinders the development of low flow liquid desiccant systems. Corrosion of the working surface reduces the system reliability and affects the overall performance (due to breakage of falling liquid film), while incomplete wetting severely weakens the heat and mass transfer performance of the system.
